Not to be confused with X-ray or X-band. | This article may be too technical for most readers to understand. Please help improve it to make it understandable to non-experts, without removing the technical details. (May 2020) (Learn how and when to remove this message) |
In physics, X-waves are localized solutions of the wave equation that travel at a constant velocity in a given direction. X-waves can be sound, electromagnetic, or gravitational waves. They are built as a non-monochromatic superposition of Bessel beams. Ideal X-waves carry infinite energy, but finite-energy realizations have been observed in various frameworks. X-wave pulses can have superluminal phase and group velocity.
In optics, X-waves solution have been reported within a quantum mechanical formulation.
